The evaluation of a link between two heroin seizures using a descriptive method is presented. It is based on the measure of the angles between two chromatograms assimilated to vectors, and interpreted using a continuous approach based on the likelihood ratio of Bayes' theorem. A complete evaluation model thus avoids the drawbacks of decision thresholds used until now to establish a link. Validation is obtained through tests and simulation methods.

Abstract
The evaluation of a link between two heroin seizures using a descriptive method is presented. It is based on the measure of the angles between two chromatograms assimilated to vectors, and interpreted using a continuous approach based on the likelihood ratio of Bayes' theorem. A complete evaluation model thus avoids the drawbacks of decision thresholds used until now to establish a link. Validation is obtained through tests and simulation methods.Pubblicazioni consigliate
